Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
IGF-1 LR3 (CAS CATO-CPTD788468) is a high-purity analytical reference standard with the molecular formula C400H625N111O115S9H3O4P and a molecular weight of 9215.60 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, IGF-1 LR3 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 9215.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
